It's not available on the template level, but you may try to use GetInstancePropertyDefinitions with the infotable returned. Please keep in mind you cannot "test" a service on the template level, you would have to create a new service in a thing and access the template services through it.

Could you please clarify - you are creating a thingtemplate and comparing the property names against a different thingtemplate? Or adding new properties to the newly created thingtemplate and comparing them to the existing ones in the same template?

You may use try/catch and run a service on the property, if it doesn't exist and you get an error, then proceed to creating one.

Such a service is not available out of the box. What I see as a workaround/potential solution, is to keep all existing properties in some datatable, then checking for a matching entry before creating a new property. Or running the GetProperties service that returns an infotable and comparing the row value.
